Shimano Dura-Ace Titanium Pedal Axle Upgrade | PD-R9100 SPD-SL

~184g after upgrade, down from 235g  |  TC11 titanium main shaft  |  Full-ceramic ball bearings  |  Pre-installed, drop-in design  |  For Dura-Ace R9100

Fully CNC machined and built around an ultra-high-strength TC11 titanium main shaft rated to withstand 1100 MPa.

The housing is 7075-T6 aviation aluminium, and the contact end that meets the original bearing uses heat-treated bearing steel, balancing weight savings with durability.

The original bearing design has been reworked, keeping part of the stock angular contact structure but pairing it with customized full-ceramic ball bearings. 

The bearings themselves are imported Japanese Kif bearings packed with imported German Klüber grease. It's a pre-installed, drop-in design, so the swap is a simple 3-step process. See instructions below.

[Installation Steps]

1. Remove the existing stock pedal axle using a wrench. Apply grease around the new axle body before inserting it into the pedal body. Installation Torque: 8-10Nm.
2. Once tightened, remove the internal adjustment screw within the hex, apply threadlocker Loctite 222/243 on the threads.
3. Reassemble the adjustment screw, tightening the screw until there is no more play when pulling on the pedal along the axle direction, and the rotation is free from obvious jamming.
